I am sure this has come up many times before, but let me ask it once again anyway. We are rewriting a VFP 9 app into VB8. One of the mains tasks of the app is printing a large number of legal documents. In VFP we stored the expressions etc to be printing in a database and at print time just called the Evaluate function on the contents of the memo field. I realize this approach does not work in VB, but I did not realize that there does not appear to be anything in VB to replace it. We thought we had a solution using JavaScript but that is being deprecated and we could not get it to work with Vista so it has been abandoned. Then we thought we had a solution using embedded expressions with Linq and XML , but that didn't work either (MS says that it will dynamically evaluate whatever is embedded in the xml but it doesn't)

We are faced with having to write all these expressions etc into module files and calling them at print time. This will mean that whenever we change a document we will also have to change the code ... ugh.

Can anyone point me in a better direction? Thanks for any and all help.
A problem is a problem only as long as it has a possible solution. Lacking that, it becomes a FACT!
